How are OpenIntro paperbacks priced?

Paperbacks are sold royalty-free: 100% of the sale price goes to
CreateSpace and
Amazon
to cover printing, listing, selling, and distribution costs.

How are resources tested?

The textbook and other resources have been tested by
a wide range of instructors. For example,
OpenIntro Statistics
has been used at over a dozen distinct colleges,
from courses at Edmonds Community College in Washington
to Princeton University in New Jersey to the Indian Institute of Management
in Ahmedabad, India. The feedback we've received from both students and teachers
help us constantly improve the textbook and our other resources.

How is OpenIntro different?

Innovation is often driven by enthusiasm, not money.
Our staff has volunteered thousands of hours
to develop the best resources and make them available
for free.
It is our mission to make educational materials available
and accessible to everyone.
We believe this is why OpenIntro has been a success:
teachers can relate to our values, they recognize
our high standards, and they enjoy knowing every student
in their classroom can access and afford the course materials.

If you are unsure whether a free product can compete, try it out.
You won't be forcing your students to pay anything extra if you
experiment with a free resource.

How can I contribute?

There are many ways to get involved or support the
movement.

1. Use open-source resources, and provide feedback
to help those resources improve.

2. Be an advocate for
open-source resources. Let other people know that
open-source resources offer benefits over
expensive alternatives: free and perpetual access
for all students before, during, and after the course.

3. If you are interested in becoming actively involved,
send one of our staff members an email to introduce yourself.
We're always looking expand OpenIntro to include new
people, projects, and ideas.
